Applicationv led October 121927, Serial No. 224:,136.4

1G for its object to pro.-

vide lan, axle of the character described' ata y low cost. Hence, the'invention provides an axle, that may be made of tubing, parts. of

which are so formed that the axlema be j mounted in a vehicle andefliciently per orm.

the functions for which it is designed.

`The invention may be contained in tubular axles that vary in theirdetails of construction and, toillustrateapractical application of the invention, I have selected anaxle containing the invention as an exampleof the vae Irions constructions that embody the invention and shall describe it hereinafter. The axle selected is shown in the accompanying draw-l y 1 the vehicle', such as to suitable springs, the

ings. v

` Fig. 1 is a-side view'of the .axle.- Fig. 2 illustrates the swaged end of the axle which is formed in advance shown in Fig. 1. Fig. 3 is an end view of the 3 axle.- Fig. 4 is a viewof a section taken on the planeof the line l1,---4 indicated inl Fig. 1.

To form'the axle shown in the igures, a tubular member is swaged vat itsends sub- 3stantially as shown inFig. 2. 'lhethicknessl p ofthe ends is increased accordingly. Forexample, it may be reduced from an outside diameter 2%," to 1,1/2 and the thickness -from V8 to about M1. This greatly increases th strength ofthe axle. l l

The axle 25 is bent to form-the angularly upwardly extending portions 26 yand the swaged end parts 2/7 are vbent as at 28 to extend at right angles to the body of the axle 25. The end parts 27 are provided with bearing members for the stub axles ofthe vehicle. In the form shown,tubes 29 having exterior diameters. substantially Athe same as the interior diameters of the end portions of the axle 25, are located within the end portions.v :5 Each endpart is bored so that the tube 29 may extend vertically through the elbow that. isy

` formed by the bend 28 and through the part 27 and so that the tube 29 will fit the inner surface of the end part 27. The tube 29 is'welded to the end part 27 torigidly secure the tube29 of shaping it to the vform A in position. The tubes- 29 form a bearing sup- Tl-:S PATENT 4.orme-a. C

The tubes-29 have enlarged lower end portions 35 that .are cylindricalfin form. Each tube 29 is provided with a flaring skirt36,

a portion of which lies within the outer surface ofthe elbow that is formed by thebend- 28.' The tube 29is Welded along the intersect-l ing line between the surfaces of the elbow and the lower end of the tube. 'A large part of the intersecting line is located on the flaring por# tion 36 and, consequently, the axle, together .with the weight'that it supports, is supported on the tubes 29 that are located in the ends of 1 the axle. The enlarged end portion 35 is adapted to receive the roller bearing 37 that is j provided with the usual conev shaped collars 38 and 39 and the cone roll'ers 40. The rollers 40 are connected togetherin the usual way as by a vcage in order to form a thrust "bearing for supporting thep'ressure that is transmit-v ted through the tube 29.

In order. to connect the axle. to the body of l tubular member, the ends of the tubular member turned to extend substantially vertically and tubes fitting the interior of the said' turned end portions of the tubular member and extending through the elbow formed at the junctionpf themain member and the substantially vertical'ends.
